The annual average tonnage mined and sold from the site are best predictions since many factors such <br />as the economy, competition, etc. greatly affect the actual sales. <br />The life of the gravel operation will be approximately 15 years. Where the gravel is mined from is not <br />easy to determine since it is very dependent upon the gold operation. If the gold operation is viable over <br />the 12 -13 years shown in the plan, a large part (60,000 tpy) of the gravel sold from the site will be the <br />waste gravel from the gold plant. If the gold operation is uneconomic, gravel will then be aggressively <br />mined from the gravel mine area as shown on Map C -2. For planning purposes, it is predicted that the <br />gravel operation will be in place 15 years at an average product sales rate of 130,000 tons per year, with <br />2 possible scenarios: <br />1) The gold mine operates for 12 years and using the same average of 130,000 tons sold per year, 60,000 <br />tons per year will come from the waste gravel from the gold plant for 12 years and all tonnage coming <br />from the gravel mine area for the remaining 3 years. Therefore, the tonnage to be mined from the <br />gravel area is 70,000 tons per year x 12 years + 130,000 tons x 2 years = 1,100,000 tons. The <br />reclamation plan map assumes that this case will occur, therefore, it shows a volume removed in the <br />gravel mine area of 1,100,100 tons. As of 2015, much of the gravel tonnage has been removed and <br />sold, therefore, future gravel sales may be furnished by the washed gravel from the gold wash plant. <br />2) The gold mine does not operate for any significant period of time. In this case, the gravel mine will <br />produce all sold material from the gravel mine area, which is basically 2,000,000 tons over the 15 <br />year period. Almost all of the previously mined areas are reclaimed from gravel mining. <br />In either scenario, front end loaders will be used to deliver the raw gravel to the crushing, screening and <br />wash plants for separation into various products. Fogger sprays will be present in all three plants to keep <br />dust down. The crusher will also employ sprays. The plants will be located to minimize impacts to the <br />town of Alma. <br />Alma Place Mine 01/15 29 <br />
